Method and System for Improving Quality of Service in Distributed Wireless Networks

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a method and system to improve the Quality of Service (QoS) in distributed wireless networks. It does so by continuously measuring interference between wireless access points, dynamically assigning radiofrequency (RF) channels to minimize interference, and grouping multiple access points into distributed antenna groups that operate on the same channel. The process is managed by a central controller, allowing the network to adapt to varying traffic loads and environmental conditions without requiring any changes to client devices.

Use CasesContent extracted from patent full text and abstract with AI.

• Enterprise Wi-Fi deployments in large office buildings, campuses, or conference centers to optimize wireless performance and handle many users.
• Public Wi-Fi networks in airports, hotels, or shopping malls where users and interference levels frequently change.
• Carrier-grade wireless mesh networks (e.g., city-wide Wi-Fi) that need dynamic traffic management.
• Smart factories or warehouses with numerous wireless devices and dynamic interference sources.
• Residential complexes or multi-dwelling units with overlapping wireless networks and dense device usage.

BenefitsContent extracted from patent full text and abstract with AI.

• Dynamically adapts wireless network configuration to actual interference and traffic, improving data throughput, minimizing latency, and enhancing overall user experience.
• Reduces both wireless and wired network bottlenecks through real-time load balancing.
• Improves coverage and reliability by forming distributed (virtual) antenna systems.
• Requires no changes or special software on client devices, ensuring easy deployment with existing IEEE 802.11/Wi-Fi compatible hardware.
• Minimizes co-channel interference, leading to higher network capacity and more robust connections even in dense environments.
• Supports both unicast and multicast traffic patterns, optimizing performance for a variety of applications.

Patent Abstract

A method for organizing an architecture of access points in a distributed wireless network includes measuring interference between the access points, assigning radiofrequency channels to the access points based on the measured interference and creating distributed antenna groups of multiple access points operating on a same radio frequency channel. A distributed wireless network includes a plurality of access points and a central controller connected to the access points via a common backbone, the central controller being configured to assign radio frequency channels to the access points according to the method.
